SPINNING-FRAME.

Application filed. March 22, 1918.

To all whom it may concern:

Be it known that 1, CHARLES D. WHITE, a citizen of the United States, residing at Norwich, in the county of New London, in the State of Connecticut have invented a certain new and useful Improvement in Spinning-Frames, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to drawing and spinning mechanisms and the immediate ob ject of said invention is to provide simple, cheap and effective means for reducing materially the wear of the traveler, ring, spindle and bolster and also to prevent the bowing out of the yarn and, incidentally, to do away with the separators now in common use. WVith these desirable ends in view I have produced the novel mechanism illustrated in the annexed drawings, in which the Figure 1 is an end elevation of the drawing rolls, showing also in proper relation to said rolls a bobbin, the ring (spinning) rail, and showing also my present improved device for preventing the bowing out of the yarn and the consequent whipping of the adjacent yarns.

Fig. 2 is a plan view of two partly filled bObbins and shows also, in proper relation to said bobbins the stabilizer rail which forms the chief feature of this present invention.

In these drawings the letter a indicates a portion of the top rail of a ring spinning frame and Z) denotes the take-up bobbin which it is assumed, is mounted on a rapidly revolving spindle in the usual, or any other practical, manner. 0 indicates the custom; ary traveler rail carrying the ring traveler (Z. Fixedly secured to the top rail a is a bracket or stand 6 on or in which are revolubly mounted the customary drawing rolls f-g and front or delivery rolls f-g.

From the said front rolls the yarn passes to what I term a carrier roll it which is journaled in a special bracket '5 secured to the stand 0 by screws 70, as here shown; the uppermost portion of the periphery of said carrier roll being, preferably, in alinement with the path of the yarn through the drawing rolls, thus locating the carrier roll a considerable distance above the customary pig-tail, guide eye and permitting the use of a specially long take-up bobbin.

Ordinarily the yarn passes from the pig- Specification of Letters Patent.

s ri Nq- 22 80- tail guide-eye direct to the traveler ring and when the bobbin is in rotation, the yarn is carried rapidly around the bobbin with a tendency to bow outward because of the centrifugal influence on said yarn and, un less some provision is made for preventing the interference of the contiguous yarns, they will whip each other and will thus become entangled and broken and in order to prevent such interference, fixed separator blades are sometime located between i the adjacent yarns.

My present invention seeks to overcome such interference by means of a novel and effective device which I will now describe. Located immediately over the traveler rail 0 and secured to said rail by means of bolts m, or otherwise, is my stabilizer rail 1% which is spaced apart from the traveler rail two inches or thereabout, said stabilizer rail being formed with circular openings 0 which are located immediately over the ring travelers and are of approximately the same diameter as the said ring travelers. In the event that the stabilizer rail n is of thin sheet metal the openings 0 may be provided by simply punching out the sheet stock and then polishing out the circumferential wall of the opening thus provided or, if the stabilizer rail is of wood, suitable circular openings may be made therein and metal bushings may be forced into the said openings.

In the operation of the described mechanism the yarn w passes from the drawing rolls to the carrier roll and thence downward (through the stabilizer ring) to the traveler ring, as indicated in dotted line in Fig. 1 of the drawings, or the yarn may be carried first to and through the traveler ring and then the yarn may be slipped into the stabilizer ring opening through tangential slots 79 leading to said stabilizer opening. So soon as the machine is started into action, and thebobbin is running up to its normal speed, the yarn between the traveler and the carrier roll seeks to bow outward because of the centrifugal influence but it (the yarn) is restrained from thus bowing outward, or rather, is limited as to such bowing outward, by the stabilizer ring 0, as will be under: stood by reference to the full line representation of the yarn in Fig. 1 in which it will be noted that, while the yarn immediately above the stabilizer ring is subjected, in some degree, to centrifugal influence, that portion of the yarn between the stabilizer ring and the traveler ring is practically straight.

The stabilizer ring thus serves, in effect,

as a separator, to prevent interference'of two adjacent yarns and it also removes the centrifugal influence entirely from the traveler ring and thus reduces, in a considerable degree, the objectionable frictional resistance of the traveler ring as the latter travels around in said ring.

The non-rotative stabilizer ring also serves, in a considerable degree, to strip from the yarn all lint which may have been carried past the carrier roll it.

' By mounting the stabilizer rail on the traveler rail no special or expensive driving mechanism is required for 'the opera tion of the stabilizer rail.

As the traveler rail 0 moves upward or downward, the stabilizers preserve at all times the same positions with respect tothe travelers; the adjacent yarns are kept from interference with each other, and centrifugal influence is removed from the traveler rings, and all of these desirable results are attained with very slight cost of construction; my present improvement beingsuch that it may be readily and cheaply applied to spinning frames of ordinary present day constructions; By providing a single straight-edged continuous stabilizing guard rail in common for a plurality of bobbins, and provided with irradially and outwardly extended substantially circular bobbin-receiving openings I am enabled to prevent entangling, twisting and breaking of any escaping threads, and of the threads before their insertion into said'stabiliz'ing guard rail due to the strong air current which surrounds the bobbins and the traveler rails, and which in the case of separate individual stabilizer or guard rings or yokes for each separate bobbin causes such threads to be forcibly aspirated or blown in between such yokes, and to be revolved and wound upon the outer periphery of the same thereby greatly increasing the'lia-bilty of'breakage of the threads, and making it difficult to connect a new length to a broken thread. By my invention this drawback is avoided by the straight edge of the continuous stabilizer or guard rail along which the thread is free to move without any undue balooning due to the freely exposed thread-supporting surface of the carrier roll h which allows the thread to move both radially and longitudinally with respect to said carrier roll h,

while at the same time being kept substantially taut, inasmuch as the thread presents ,but a two-legged angular path from the drawing rollers to the traveler by which means any undue slack or ballooning of the thread is avoided or taken up without any special tightening or' taking-up devices. Any escaping thread may therefore, be easily readjusted and re-inserted into the apertures of the stabilizing guard rail n and without its becoming entangled or broken,

and whipped around the guard rail.

my invention, I

rality of drawing rollers, a freely rotatable thread guide having a freely exposed thread-supporting and guiding surface su'b stantially flush with the working surface of said drawing rollers, and intermediate the apertured part of said stabilizing guard rail andsaid drawing rollers and in spaced relation therewith, and a substantially straight length of threadextending' from said carrierrroll to said guard rail,cand a substantially straight length of thread extending from said carrier roll to said drawing rollers. i

3. In a spinning frame the combination with an apertured traveler rail of acontinuous apertured straight-edged stabilizing guard rail in parallel spaced relation with said traveler rail and connected therewith and having substantially circular apertures registering with the apertures of said traveler rail, substantially smooth irradially divided inner wall portions surrounding the apertures of said guard rail, and bobbins substantially axially arranged in the register-ing apertures of said rails.
